摘要
本文采用UHPLC-Q Exactive轨道肼高分辨质谱建立了快速、灵敏的液质联用方法在线快速鉴定黄芪建中汤的化学成分,构建了较为全面的黄芪建中汤化学成分谱,用于该复方的质量评价。依据离子峰的保留时间、精确分子量和多级质谱碎片,与对照品及文献报道数据比较,对黄芪建中汤的整体化学成分进行了在线快速鉴定。共鉴定了黄芪建中汤中71种化学成分,主要包括皂苷类和黄酮类,另外还有个别生物碱类和酚类化合物等。这些成分中,来源于黄芪的有20种、白芍14种、甘草37种、生姜3种、桂枝大枣各2种,为黄芪建中汤的质量控制以及药效物质基础研究提供了科学依据。
This study was designed to establish an ultra-liquid chromatography-mass spectrometry method for the reliable identification the multiple chemical components in Huangqi Jianzhong Tang （HQJZ）. The ultra- high performance liquid chromatography coupled with hybrid quadrupole-orbitrap mass spectrometry method was applied to identify the chemical constituents in the HQJZ rapidly. A total of 71 compounds including two major categories of saponins and flavonoids were identified or tentatively deduced on the basis of their retention behaviors, fragments of multistage mass spectrometry or by comparing with reference substances and literatures. Among them, 20 compounds were from Astragali Radix, 14 were from Paeoniae Radix Alba, 37 were from Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, 3 were from Rhizoma Zingiberis Recens, 2 were from Cinnamomi Ramulus and Jujubae Fructus, respectively. The LC-MS method was used to qualitatively analyze the chemical constituents of HQJZ, which provides a scientific basis for the quality control of HQJZ.
